An isolation transformer might help with the safety aspect, but it may not help much with the noise.

Maybe he has water or heating pipes in his flat. Sometimes you can also use these as earthing.
(Even if this is not optimal, it can help).

 ;D we only have air conditioner, its hot even in winter  :)

i have a question off-topic, how much power can the function generator output?
i looked in the datasheet of the device but nothing mentioned, 

DavidAlfa:
Close to nothing. it's just for signal/very low power.
There's a 50 Ohm resistor in series, any load will bring the amplitude down.

and for the last 2 days, i was playing with a speaker connected directly to it and was happy because it had a loud sound, where i can find all diagrams before i break something?

Do you have metal drain pipes?  They do make a very good earth ground.

Once you do hook up a ground, if you can, it would be an idea to put an RCD/GFI in line with your lab power supply.
